1)-3x + 4 = -10 + 5(-7 - x)-3x + 4 = -10 - 35 - 5x-3x + 4 = -45 - 5x-3x + 5x = -45 - 42x = -49x = -49/2x = -24.5
2)x/2 + x/4 = -3/2Multiply every term by 4 to get rid of the fractions:4(x/2) + 4(x/4) = 4(-3/2)2x + x = -63x = -6x = -6/3x = -2
1)
-3x + 4 = -10 + 5(-7 - x)
-3x + 4 = -10 - 35 - 5x
-3x + 4 = -45 - 5x
-3x + 5x = -45 - 4
2x = -49
x = -49/2
x = -24.5
2)
x/2 + x/4 = -3/2
Multiply every term by 4 to get rid of the fractions:
4(x/2) + 4(x/4) = 4(-3/2)
2x + x = -6
3x = -6
x = -6/3
x = -2
